Fair Isaac Offers "Deepest Rules Platform" According to Independent Research Firm in New Business Rules Report

Issued on January 4, the recent Forrester Wave Vendor Summary is entitled "Fair Isaac Is The Deepest Business Rules Platform." The report notes that "Fair Isaac Blaze Advisor provides the most extensive range of rules modeling tools in the industry, strong domain description tools, and strong tools for creating rules maintenance applications for business users."

"Fair Isaac is a Leader in business rules platforms, and its Blaze Advisor is a broad, Rete-based platform for business rules application development and enterprise rules management," writes John R. Rymer, vice president at Forrester Research, in "Fair Isaac Is the Deepest Business Rules Platform," Forrester Research, Inc., January 2006. "Fair Isaac offers the strongest multi-platform features, enabling developers to use the same rules language and modeling tools to generate applications for Java, .NET, and mainframe COBOL."

Blaze Advisor 6,1 demonstrates Fair Isaac's continued investment in delivering the most comprehensive platform for business rules application development and Enterprise Decision Management (EDM).

Available immediately, Blaze Advisor 6,1 integrates Rete III rules execution technology gained when Fair Isaac acquired assets of RulesPower, Inc. in 2005. Rete III is designed for data- and rules-intensive organizations where optimal performance is critical. Combined with Blaze Advisor's existing performance optimization capabilities, powerful rules repository, developer tools and templates for business user rules management, the integrated system helps organizations process and execute complex, high-volume business rules faster and more efficiently than other rules management systems.

"Blaze Advisor's high-volume processing power is balanced with a platform that gives business users greater control and ensures consistency in managing decisioning applications," said Mark Layden, vice president and general manager of Enterprise Decision Management software at Fair Isaac. "Our rules technology continues to provide a foundation for EDM that is focused on helping businesses reach new levels of agility in an increasingly complex, competitive and regulated global economy."

With a centralized enterprise repository for business rules, powerful query and update tools, multi-platform and multi-lingual support, and documented best practices, Blaze Advisor 6,1 gives organizations a clear process for quickly replicating their decision strategies across business systems to improve business operations. The new features also will enhance the performance of other Fair Isaac solutions in which Blaze Advisor is embedded, including Falcon™ Fraud Manager, Falcon™ ID solution, and Capstone^® Decision Accelerator.

Blaze Advisor 6,1 is part of Fair Isaac's software and solutions for Enterprise Decision Management, which combines data analytics, modeling and policy-level control to let companies define and manage their automated business systems for improved efficiency and greater profitability.
